METHOD OF OPENING AND CLOSING FARM-GATES BY APPROACHING VEHICLES.

Specification of Letters Patent No.

To all whom 'it may concern:

Be it known that I, EZRA G. ROWLAND, of the town of Phelps, in the county of Ontario and State of New York, have invented a new and useful Improvement in a Self-Operating Gate or Gates; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification.

Figure 1, represents a perspective view of the gate and improvement, Fig. 2, represents a transverse section, and Fig. 3, represents the operation of the levers used in opening and shutting the gates.

To enable others to make and use my in vention I will describe its construction and operation.

A, I, represent the gates constructed as ordinary sliding gates, are made.

13, B, represent the casing around the gates.

I, I, I, represent the frame work or box which contains the apparatus operating the gates, which may be constructed of plank or other material from 6 to 10 inches high to be covered with plank and so placed in the ground that the top of the plank covering is even with the surface of the ground.

C, C, represent a lever upon hinges which the carriage wheel acts upon to open and shut the gate.

H, H, represent a rod which connects the lovers (1, C, with the levers E, E. The rods are attached to the levers C, C, by a joint. The other end is connected by a slot resting upon the end of levers E, E. Levers E, E,

can be constructed of wood or metal. They act upon the pivots K, by means of the rods H, H, and the levers C, C, which act upon the levers D, D, which pass through a slotin the top of levers E, E. Levers D, D, can be made of wood or metal of sufiicient length to connect the levers E, E, with the chain F, F. Levers D, D, are fastened by a pivot at J, and the opposite end fastened to the chain F, F, one lever to the lower and the other to the upper chain as in Fig. 1.

The chain F, F, is endless and passes around two friction pulleys G, G, and are fastened to the gates by means of the two rods D, D, which rods move through a slot in the planks under the gates. WVhen the carriage approaches the gates, the wheel passes upon the lever C, at the right, which operates upon the rod H, pressing down the lever E, which moves the lever D, which acts upon or moves the chain F, F, which operates upon or separates the gates; and as the carriage passes through the gates, the wheels at the right, pass upon the lever C, which by its connection as above described with the lever D, and the chain, causes the gates to come together or shut.

lVhat I claim as my invention and desire to secure by Letters Patent, is

The connections above described of the levers D, E, and the endless chain as connected with the gates, for the purpose of forming self opening and shutting gates.
